Wet samples? Not a Problem.
Raman spectroscopy results from light scattering from samples, not from the absorption of light. It is therefore unperturbed by moisture or wet samples, unlike near infrared absorption techniques. There’s no need to dry samples — a major advantage when testing in the field, especially with volatile organics present.
Point and Shoot
Point – Shoot – Analyze – Secure.
In most cases, samples are tested through plastic, glass or quartz. Direct contact is also possible, but often there’s no need even to remove the sample from its packaging. For hazmats, contraband, explosives or other threats, testing through packaging is a critical advantage inherent to the Raman method. There’s no sample handling, no pouring of harmful materials into cups or mixing.
Raman technology is non-destructive, causing no damage to the sample and therefore posing no liability to your inventory.
Easy to use
Paramount for portable analyzers! Once the analyzer is configured with an appropriate library, it becomes an easy to use, in-field device for rapidly identifying unknown compounds, or verifying a compound is “as labeled.” A simple “MATCH” or “NO MATCH” result is provided in seconds. For “no matches” operators can set aside those samples for further analysis.
Handling’s a cinch – for all types of samples.
Often field conditions present sampling challenges, such as awkward angles or materials in the form of liquids, gels, powders or solids in irregular containers. The SciAps Raman models can be equipped with a variety of attachments to make sample testing easy. Included extensions include:
• “Point and shoot” attachment. Simply make contact with the product and push the START button. Three focal length settings are provided, for testing through thin plastic, thick or doubled plastic bags, or plastic or glass bottles for liquids.
• Standard 8 mm vial holder, ideal for liquids. Fill the vial, drop it into the holder, and presto — identify your compound in seconds. Also used for calibration check standard.
• Right-angle measurement head makes testing material in plastic bags effortless. Also ideal for samples on a work surface. There are three settings for optimum sampling and disposable caps to prevent cross contamination
